Traffic signal release system and method based on wireless local area network

Abstract

The invention relates to a traffic signal release system and method based on the wireless local area network. The method comprises the followings steps: obtaining a traffic control signal or generating a traffic sign signal, assembling, encrypting, wirelessly releasing the signal, and decrypting and displaying the signal after the signal is received by a terminal. The traffic signal release system based on the wireless local area network comprises a traffic signal source and a terminal processing device. The system is simple and practical, and easy to build, realizing of orderly regular traffic without vision blind areas and sight obstruction during driving is facilitated, the system and the method can be used for quickly building a warning sign in sudden traffic accident or temporary construction sections, high portability, high release efficiency and long distance are achieved, a warning effect is obvious, the blank of traffic signal release is filled, and voice prompt is realized when a person does not concentrate on driving, so that accidents are greatly reduced, and traffic safety is effectively guaranteed. Traffic signal information is transported in an asymmetric encryption mode, so that high safety and reliability are achieved, and traffic disturbance caused by the fact that other persons release fake information is effectively eliminated.

Description

technical field [0001] The invention relates to a traffic signal distribution system, in particular to a traffic signal distribution system and method based on a wireless local area network. Background technique [0002] With the improvement of people's living standards, the number of vehicles is increasing alarmingly, causing road congestion. In order to regulate travel and ensure road traffic safety, it is a common practice in various countries to set up various traffic lights and signs on intersections and roads. Indicator lights and signage have made great contributions to road safety, but both indicator lights and signboards need to be installed on fixed facilities, which cannot solve the notification of sudden traffic conditions. With the rapid development of electronic technology, the ancient Placing warning signs directly at the accident scene has become very backward, and the indicator lights and signs installed on fixed facilities will exist beyond the visual range...

[0002] With the improvement of people's living standards, the number of vehicles is increasing alarmingly, causing road congestion. In order to regulate travel and ensure road traffic safety, it is a common practice in various countries to set up various traffic lights and signs on intersections and roads. Indicator lights and signage have made great contributions to road safety, but both indicator lights and signboards need to be installed on fixed facilities, which cannot solve the notification of sudden traffic conditions. With the rapid development of electronic technology, the ancient Placing warning signs directly at the accident scene has become very backward, and the indicator lights and signs installed on fixed facilities will exist beyond the visual range, or are easily blocked and cause blind spots. Distraction, etc. will also lead to traffic accidents, leaving a painful lesson

Some of the wireless traffic signal release equipment currently produced have low security and are easy to be hacked to release false traffic signal information
